Volvo Forums

Best is buy a used assembly (Valeo) from ebay or junk yard.
Ebay is about $70, junk yard about $25.

Tips: watch this youtube video:

Same question but asked in a different forum.
I got 2 separate answers, one said 4 mm, the other said 3 mm.

Yes, Castrol HD does not have MOS2 as it seems, good to go. MOS2 kills the tripod joints.

FYI,

MOS2 does not kill CV joint. Do a little google search "MOS2 CV Grease" and you will see MOS2 is in the CV grease for many cars.

You'll notice soon enough if you put molybdenum disulphide grease into tripod joint. Not true. Mechanically, same engineering issue, same lubrication requirement for both inner and outer CV ball bearings. The problem with INNER, especially L side: it is close to engine heat. I usually use the greas...

Keep the orientation the same. The side faces the bolt has a slight indentation.

My crush washer has been re-used at least 20 times, zero leak. Tighten it, then add a bit, do not over-tighten it.

The round part where the bolt goes in stays with the engine.

If you look carefully at the 2nd photo above, you will see the broken part.

Actually you don't need 30731007.
All you need is a silicone hose of appropriate I.D.
See the other thread I posted a question and someone answered it.

Unless someone convinces me, I see no need to replace this piece.

I removed it from the car and the 3 items (EVAP, Vacuum, and the wire loom) seem to be fine w/o this bracket.

I found the answer on reddit!
